This study found that young adults who consume more alcohol and engage in frequent simultaneous use have higher expectancies and pleasure from simultaneous use of alcohol and e-cigarettes. It suggests that positive reinforcement may be involved in the patterns of simultaneous use.
Background: Young adults' use of alcohol and e-cigarettes are of public health concern, as they report among the highest prevalence for use of both substances. Many young adults use alcohol and e-cigarettes simultaneously (i.e., at the same time with overlapping effects) despite heightened risk for adverse effects. Objectives: This study assessed simultaneous use expectancies and changes in pleasure from e-cigarettes as a function of alcohol consumption and simultaneous use frequency. Participants (N = 408; Mage = 23.64 years; 52.7% female) recruited through Amazon MTurk completed measures of alcohol and e-cigarette use, and expectancies, pleasure and frequency of simultaneous use. Results: Separate linear regression models revealed that alcohol consumption was positively associated with expectancies for simultaneous use of e-cigarettes/alcohol and pleasure from simultaneous use (ps <= .015). As individuals engaged in simultaneous use more frequently, they also reported greater expectancies for, and increased pleasure from, simultaneous use (ps < .001). Conclusions/Importance: Expectancies for simultaneous use may be greatest among young adults who consume more alcohol and engage in simultaneous use more frequently. Increased pleasure from e-cigarettes while drinking suggests that positive reinforcement may be implicated in simultaneous use patterns. Future research should examine the role of pleasure in simultaneous use trajectories.
